BACKGROUND Clinical studies have shown that transthoracic cardioversion of atrial fibrillation is dependent on achieving adequate current flow to the heart, which is dependent on transthoracic impedance. When multiple standard cardioversion fails to restore sinus rhythm in patients with atrial fibrillation the double sequential transthoracic shock may be an(More)
Torsade de Pointes (TdP) is an atypical ventricular tachycardia that occurs in the setting of QT interval prolongation which may be an inherited or acquired abnormality. TdP is a recognized complication of bradyarrhythmias, specifically atrioventricular block. However, sinus node dysfunction is a rare cause of syncope associated with TdP. Experimental(More)
The efficacy and safety of intravenous propafenone for conversion of recent-onset and chronic atrial fibrillation was assessed in 46 patients. 40 with atrial fibrillation associated with or without structural heart disease (mean age 63 +/- 14 years) and 6 patients with atrial fibrillation related to the Wolff-Parkinson-White syndrome (mean age 34.8 +/- 13(More)
